Chapter 1 General Information

2 System Information

Boot Priority

Some boards have preferred slot locations. Consider the boot order when choosing the accessory board slot in which to install the accessory board.

This is the default boot priority for the LH 6000/6000r:

1. IDE CD-ROM drive with a bootable CD-ROM

2. Flexible disk drive with a bootable flexible disk

3. HP NetRAID controller or integrated Embedded SCSI controller

4. PCI boards in slots in the following order: 8, 7, 6, 5, 4, 3, 2, and 1

Change this boot order using the Setup utility.

IRQ Settings

The BIOS automatically assigns the IRQs (hardware interrupts) for each PCI slot and embedded device in the HP NetServer during boot. These assignments trigger the NOS to enable the APIC (Advanced Programmable Interrupt Controller). APIC takes advantage of the expanded set of non-conflicting IRQs for those accessory boards requiring more than one IRQ per slot. APIC provides up to four dedicated interrupts for each PCI slot.

These automatic IRQ assignments can be changed in the setup screen (F2).

Connector Pinouts

Unless otherwise noted, the following features apply to all models. Some features are factory installed; others are optional.

Video Connector Pinouts

The built-in video uses the standard 15-pin analog display pinout configuration. The pinouts for your monitor may vary. For the pinouts for your monitor, refer to the manual that came with your monitor.

DIMM slots on System Board

l Add paired DIMMs of these sizes:

◊ 128 MB

◊ 256 MB

◊ 512 MB

◊ 1 GB

l Memory of equal size must be added in pairs.

l You can mix DIMM sizes. For example, you may place a 1 GB DIMM pair next to a 128 MB

DIMM pair.

l Add paired memory in any order to the eight slots.

Chapter 2 System Information

l Maximum configuration is 8 GB.

l Do not rock the DIMM into place, but apply firm and even pressure until it is seated in the

socket.

l Use only HP-supported DIMMs.

The installation procedure is the same for the rack-mount and the pedestal HP NetServers once you gain access to the system board assembly. While you can perform memory installation in the rack or in the pedestal, it is recommended that you remove the system board assembly in order to install components. If you install memory without removing the system board assembly, the DIMM slots region of the system board is accessible when the bottom cover of the LH 6000r is removed and the left cover of the LH 6000 is removed.

CAUTION Wear a wrist-strap and use a static-dissipating work surface connected to the

chassis when handling components. Ensure the metal of the wrist strap contacts your skin.

Mass Storage Guidelines

This HP NetServer has a flexible mass storage system. You can install up to six hot-swap devices in the primary hot-swap mass storage cage and you can install an additional six hot-swap devices in the optional, secondary cage.

◊ Verify correct operation

◊ Shut down power to hot plug slots

CAUTION Do not attempt to install or remove non-hot plug PCI boards with the HP NetServer

in any kind of sleep state, or a system crash or hang may occur.

l Slots 1, 2, 3, and 4 are non-hot plug; slots 5, 6, 7, and 8 are hot plug.

l For optimal performance, add PCI boards to slots 7 and 8, which at 66 MHz and 64 bit, are the

fastest.

l Consider the boot priority prior to installing accessory boards, but after configuring the HP

NetServer.

l Some accessory board outputs may exceed U.S. National Electrical code (NFPA 70) Class 2 or

power source limits and must use appropriate interconnecting cabling in accordance with the National Electrical Code. (All Hewlett Packard boards comply with Class 2.)

l You can configure the HP NetServer to boot from a PCI-based DAC inserted into a PCI slot.

Use the Symbios Configuration Utility to select a different PCI slot when scanning for boot devices.

l Slots 7 and 8 accept universal boards. Universal boards automatically switch to accept power

from a +5.0 or +3.3 VDC.

Hot Addition and Replacement of Hot Plug PCI Boards

The PCI Hot Plug option is NOS-dependent. To use the Hot Plug option, the PCI board must have a hot plug compliant driver and a Hot Plug Utility for the respective NOS. The Hot Plug Utility is used to turn power off/on to the PCI slot, while the HP NetServer continues to operate normally.

Chapter 2 System Information

NOTE Hot Removal or online deletion of an adapter board and reconfiguring of that

adapter from the HP NetServer is not supported.

Refer to the PCI Hot Plug Replacement procedures in HP NetServer Navigator CD-ROM for the NOS you are using.

Online Replacement, Hot Swapping, of a PCI Adapter

NOTE You can Hot Swap an adapter only if it is the passive adapter, or inactive adapter of

a fault-tolerant pair.

Remote Control (Top Tools) Board

The HP Remote Control board supports HP TopTools software and comes installed from the factory in PCI slot 2, due to its boot order (Bus 5) and a required cable connection to the I/O board. The I HP TopTools Remote Control card is inserted into connector J1F1 on the I/O board.

HP NetRAID Guidelines

This HP NetServer contains an embedded dual-channel RAID controller, which puts the power of the HP NetRAID series of disk array controllers in the HP NetServer.

HP NetRAID technology lets you link multiple hard disk drives together to provide faster access and/or increased data reliability. With the embedded RAID controller, you can configure your linked drives as RAID (Redundant Array of Independent Disks).

Disk drives in the hot-swap mass storage cage may be used as either standard mass storage, or configured together as a RAID array.

This HP NetServer is shipped with SCSI A channel enabled as a RAID channel, and the included hot-swap drive is not configured. You can either disable SCSI A channel as a RAID channel, or configure the drive(s) in the hot-swap cage as a RAID array.

To disable SCSI A channel:

• Exclude SCSI A channel from the embedded RAID controller, as follows:

1. Restart the HP NetServer.

2. When you see the message "Press [F2] to enter SETUP" on the monitor, press the [F2] function key.

3. When the Setup Utility menu appears, use the up and down arrow keys to highlight "Included SCSI A Channel Yes]."

4. Use the +/- keys to change it to "Included SCSI A Channel [No]."

5. Press the F10 function key to save and exit.

6. Answer "Yes" to the question, "Save configuration and exit now?" The HP NetServer will start up again, and HP Navigator will restart.
